Pipe for discharging sewage and preparation method of pipe

Abstract

The invention discloses a pipe for discharging sewage. The pipe is prepared from the following raw materials in parts by weight: 60-90 parts of unsaturated polyester resin, 13-19 parts of polyphenylene sulfide, 6-14 parts of liquid polyisoprene rubber, 3-9 parts of calcium carbonate, 2-6 parts of asbestos powder, 4-9 parts of sodium selenite, 2-6 parts of polychlorotrifluoroethylene, 3-6 parts of basalt fibers, 2-9 parts of polyvinyl acetate, 2-5 parts of epoxidized linseed oil, 1.5-7 parts of a POE (polyolefin elastomer), 1-4 parts of an anticorrosive agent and 1-3 parts of a dispersant. The pipe has the advantages that a preparation method is simple and easy to implement, the cost is lower, and raw materials are available; the unsaturated polyester resin, polyphenylene sulfide, the liquid polyisoprene rubber, calcium carbonate and the like are mixed to be used as materials of the pipe; the unsaturated polyester resin has excellent chemical stability, heat and cold resistance, weather resistance, hydrophobicity and low surface tension and does not produce substances polluting the environment, and the anticorrosive agent is added, so that corrosion resistance of the inner surface of the pipe can be significantly improved.

Description

technical field [0001] The invention belongs to the field of pipeline materials, and in particular relates to a sewage drainage pipeline and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the economy, our environment has also been damaged to varying degrees, among which water pollution is particularly serious. The sewage mainly comes from various industries such as chemical energy, metal smelting, automobiles, and medicine. Although it will be discharged to a certain standard after certain treatment, it will still contain a large amount of acid and alkali, heavy metal ions, and bacteria. During the drainage process, the pipeline will be continuously corroded and infected, and the pressure resistance and strength are not enough, which will shorten the life of the pipeline, which is not only not environmentally friendly, but also uneconomical, and will waste more manpower and material resources. Therefore, it is of g...
